Advanced Placement classes, often referred to as AP classes, are college-level courses offered in high school. They allow students to study subjects in greater depth and rigor than standard classes. By taking these courses, students can earn college credit or advanced placement in college courses, depending on their performance on the AP exams. These classes cover a variety of subjects, including math, science, history, and languages. They are designed to challenge students and prepare them for the academic demands of college. Many high schools offer these courses, and they can enhance a student's college application by demonstrating a commitment to academic excellence.
